I am having some troubles setting up the issue tracker link with bugzilla. The problem manifests itself when I test the connection, or when I select the drop-down arrow generated in the commit messages. There is no problem clicking the link, however. My settings look like this:

Connection Type:

Bugzilla

Display Name: *

Server URL: *

Username:

Password:

Issue Id Pattern:*

Use general regexp, e.g. #(\d+)

I have checked the server logs and the only entry I can find regarding this looks like so:
[2010-09-17 14:49:38,368] INFO - eTracker.AbstractIssueProvider - Failed to fetch the issue: 3679, reason: HTTP server returned unexpected status: Bad Gateway, connection: "Bugzilla"

Any ideas what is going on? Do I need to configure bugzilla somehow? Our bugzilla server is running version 3.0.6 and TeamCity version is 5.1.4.
